OpenSSL: install .pc files from the exporters subdir

The .pc files generated in the root directory are used as part of the
build; they should never be installed. Use the versions from the
exporters subdirectory--which should be installed--as the .pc files
which are distributed with FreeBSD. This avoids the need for "fixing up"
these files after the fact (see `crypto/openssl/BSDmakefile` for more
details as part of this change).

Garbage collect `secure/lib/libcrypto/Makefile.version`, et al,
as they're orphaned files. They were technically unused prior to this
change as the vendor process properly embeds the version numbers in
various files, but this commit formalizes the removal.

This correction/clarification on the .pc files will be made in an
upcoming release of OpenSSL [1].
